an article reported on a long - term study of the effects of hurricanes on tropical streams of a forest. the study shows that a hurricane had a significant impact on stream water chemistry. the following shows a sample of 10 ammonia fluxes in the first year after the hurricane. data are in kilograms per hectare per year. complete parts (a) through (c) below. 91 74 144 144 170 112 57 57 86 152 a. find the mean. the mean is 108.7. (type an integer or decimal rounded to one decimal place as needed.) b. find the median. the median is 101.5. (type an integer or decimal rounded to one decimal place as needed.) c. find the mode(s). select the correct choice below and, if necessary, fill in the answer box within your choice. a. the mode(s) is(are) (use a comma to separate answers as needed.) b. there is no mode.

Answer

Explanation:

Step1: Recall mode definition

The mode is the value(s) that occur most frequently in a data - set.

Step2: Count frequencies

The data set is 91, 74, 144, 144, 170, 112, 57, 57, 86, 152. The number 57 appears 2 times and 144 appears 2 times, and all other numbers appear 1 time.

Answer:

A. The mode(s) is(are) 57,144
